Stabilenka®

Woven Fabricsfor Reinforcement

and Separation

HUESKEREngineering with Geosynthetics



Soil Reinforcement withStabilenka®

When a high tensile strength geosynthetic is

installed in soils which have been placed andcompacted in layers, it forms a composite ofgeosynthetic and soil. The geosynthetic acts asa reinforcement due to its high frictionalproperties and its ability to absorb tensile forces.

Stabilenka®, a fabric of great tensile strengthproduced from high modulus polyester, withstandshigh tensile forces even at low elongation.Thus, it is suitable in many applications wheresoil reinforcement is required in earthworkshaving small, acceptable deformations.

Embankmentson Soft Subsoil

When constructing embankments on softsubsoils such as peat or clay, there is often a riskof bearing capacity failure when constructionrate is rapid and the shear resistance of thesubsoil is exceeded. By installing Stabilenka®

between the subsoil and embankment fill, thesoil's bearing capacity is greatly increased.

Stabilenka

®

thus guarantees the external stabilityof the embankment until the subsoil is finallyconsolidated and an adequate soil shearstrength is achieved.

Stabilenka®

in Hydraulic Engineering

Soil bearing capacity can also be quickly improvedwith Stabilenka® for hydraulic engineering projects

such as the construction of dikes, breakwaters or jetties. Stabilenka® can be produced to size in largereinforcement mats and then simply laid by ship or bycable-laying frames. Large bags or tubes can also bemade of Stabilenka® which can be filled with sand andare mainly used to prevent soil erosion.

Retaining structures of soil are easily constructed withStabilenka®.

Embankments with Stabilenka® remain stable. Details showsfabric deformation during initial settlements.

Without Stabilenka® anembankment can collapseand/or the subsoil can besqueezed out from beneaththe embankment.

Steep slopes can collapsewithout Stabilenka®.

Reinforcement in LandfillConstruction

The mineral sealing layers of a waste disposalsite can only accept loadings that produce lowstrains in order to avoid tracking. Stabilenka®,when properly designed and installed belowthe sealing layer, can prevent unacceptably highstrains during settlement of the subgrade

or waste. Stabilenka® can also be used asreinforcement for steep slopes of a landfill.

Reinforced EarthRetaining Structures

When retaining structures or steep slopes arerequired at angles greater than permissibleform the shear strength of the soil, stability canbe achieved by reinforcing with horizontallayers of Stabilenka®.

Wrap-around walls where Stabilenka® formsthe facing can be landscaped and planted.When concrete elements are used for faciadesign, Stabilenka® is usually installed only asreinforcement strips in the soil.

Economical Constructionwith Stabilenka®

If Stabilenka® is used for reinforcing soft,low-bearing capacity subsoils, there is noneed for soil excavation, conventional soilstabilization or long consolidation periodsdelaying construction. Even on low shearstrength subgrade Stabilenka® can be used to

construct safe retaining structures.

In all cases, one saves time and money.Stabilenka® is easy to transport and can beinstalled simply and easily without specialistequipment.



Stabilenka®

High Strength / High QualityWoven Geosynthetic

Stabilenka® is a high quality woven fabric madefrom polyester yarns in the longitudinal (warp)direction and polyamide, or optionally polyester,in the transverse (weft) direction. It is available

in nine standard types with varying tensilestrengths up to 1000 kN/m in the warp direction.

By using high modulus polyester multifilamentyarns in a patented straight warp process,Stabilenka® always maintains high tensile forcesat low elongation. As polyester yarns have verylow creep potential, creep strain is limited to 1%after two years.

Stabilenka® is permeable and provides highlong-term resistance to microbial, chemical andmechanical damage.

Stabilenka® a reliableConstruction Material

Since its first installations in 1974, Stabilenka®

has proved its high standard of quality andindustry acceptance in hundreds of projects.Long term records have been kept on numerous

projects to obtain test data and experience forthe design and computation of new soilfoundation structures utilising Stabilenka®.

Detailed project studies and technical informationleaflets are available for engineering designwith Stabilenka®.

Stabilenka® is a joint product from Colbond b.v.and HUESKER Synthetic GmbH; together, theyprovide high quality geosynthetics as well asprofessional assistance in the project planningstage and on-site assistance when required.
